[EXPANDSD] Join your external SD with internal SD!

---

WARN: For developer only.

attachment is the EXPANDSD script.

Why use it?
So many applications use /sdcard for mass data storage(gameloft, navigation...),
but I9100's internal_sd size is limit to 11G, so we need external_sd's space.
But these applications dosen't know how to use external_sd, old method is hack the apk for external_sd, but this will change apk's signature, and need smali/baksmali to work. My method work in system level, don't need change any apk file.

How to use:
1.make expandsd.ownhere dirctory in external_sd root directory.
2.move internal_sd's directory(for example:/gameloft) to expandsd.ownhere
3.run init_expandsd.sh

Theory：
use 'mount --bind' feature, bind external_sd's dir to internal_sd.
Because the sd card using fat32 partition format, the 'ln -s' command does not work, so the "mount --bind" is the only way to dynamically change the directory content.

Hi mate,

Thks for your shares. I have a question. How run init_expandsd.sh?

I tried gscript and init.d, but doesn't seem to be working

woohoo a great dev has come. glad you got here mate! love your work on Desire section.

you can try to use terminal emu, just type su then navigate to folder where the script located, then type sh init_expandsd.sh then enter. this might do the trick to execute .sh

Does it work for you?

It's a great idea thanks a lot for your work. I was wondering why ln was not working.

But too bad it does not work for me, i get the following error :
[1] Segmentation fault

Do you have any idea why ?

Thanks again

problems when connecting phone to pc

hi,
tried the "mount --bind" in order to try your script.
works fine. the directory contents is shared between the 2 path's,
but i have a problem when i connect the phone to a pc.
when i try to disconnect, the sdcard and external_sd are not
available anymore until i reboot the phone

note: the commands that i have executed are:

mkdir /mnt/sdcard/external_sd/foo
echo "test" > /mnt/sdcard/external_sd/foo/test
mkdir /mnt/sdcard/foo
mount --bind /mnt/sdcard/external_sd/foo /mnt/sdcard/foo

Can this script be placed in init.d folder for autorun at boot?

Edit: sorry, already answered above: no, it cannot.
